Answer:
This question lacks options, options are:
A) ATP
B) NADP
C) Pryuvate
D) glucose
E) acetyl-CoA.
The correct answer is C) Pyruvate.
Explanation:
Pyruvate is a very important compound for the cell since it is a key substrate for energy production and glucose synthesis (neo-glycogenesis), that is, pyruvate is the end product of glucose breakdown in glycolysis. Before entering the mitochondria, it can be converted to lactate, through an anaerobic reaction (in the absence or under oxygen supply) of low performance in energy production, when the main pathway is interfered with. It can also be converted to the amino acid alanine. Within the mitochondria, it can be transformed, by pyruvate dehydrogenase (PDH), into acetyl-coenzyme A (acetyl-CoA), the entry point (substrate) of the Krebs cycle. In addition, by means of pyruvate carboxylase, it can be transformed into oxalacetate, which constitutes the first step in neoglycogenesis.
Answer:
Two Pyruvate, two NADH, and two ATP molecules are the products of the glycolysis which are sent to the mitochondria of the cell.
Explanation:
Glycolysis is a first step of cellular respiration in which glucose molecule is broken down and producing pyruvate, NADH and ATP molecules. These three products are sent to the mitochondria of the cell for further energy production for the cell. Mitochondria is also called power house of the cell where energy is produced in the form of adenine tri phosphate with the addition of oxygen which comes from the process of breathing.

The complementary strands of DNA ______________ to form a ____-shaped replication fork New ________ pairs are formed according to base pairing rules Each double-stranded DNA is made of one _____ strand and one __________ strand of DNA
Answer:
The complementary strands of DNA ____Unwind__________ to form a _Y___-shaped replication fork New __Neucleotide base______ pairs are formed according to base pairing rules Each double-stranded DNA is made of one _old____ strand and one ___new_______ strand of DNA
Explanation:
Central dogma is the process by which proteins are synthesized from genetic information. It comprises of replication, transcription and translation. In replication the new copy of DNA is synthesized.
The double stranded DNA is unwound by helicase enzyme.A primer is added by RNA polymerase to start replication by DNA polymerase.DNA polymerase can add the nucleotides in only in 5' to 3' direction so it synthesizes one strand of DNA continuously known as "leading strand" and one strand in fragments known as "lagging strand"Ligase enzyme join the fragments of lagging strand.The new DNA molecule contains the one old strand and one new strandDuring DNA replication, strands unwind to form a Y-shaped fork as new nucleotide pairs form. This results in two DNA molecules, each containing an original and a new strand, in a process termed semiconservative replication.
Explanation:The complementary strands of DNA unwind to form a Y-shaped replication fork. New nucleotide pairs are formed according to base pairing rules. Each double-stranded DNA molecule is comprised of one parental strand and one newly synthesized strand of DNA.
DNA replication starts when enzymes called DNA helicases initiate the unwinding of the DNA helix at specific sites known as origins of replication. This process results in the formation of two replication forks that look like the letter 'Y'. Single-strand binding proteins then stabilize the unwound DNA to prevent the two strands from reannealing. Following this, DNA polymerases catalyze the formation of phosphodiester bonds between new, complementary nucleotides that are hydrogen bonded to the parental strands. The result is the creation of two new double helices, each with one old and one new strand, a process known as semiconservative replication.
What is the name of the microtubule-organizing center found in animal cells as an identifiable structure present during all phases of the cell cycle?
In animal cells, the microtubule-organizing center present during all phases of the cell cycle is known as the centrosome. It houses a pair of centrioles, which play a vital role in cell division and the extension of microtubules as cilia or flagella. The centrosome is therefore an essential structure in both the cell support system and in its division and movement processes.
The microtubule-organizing center found in animal cells that is present throughout all phases of the cell cycle is called the centrosome. The centrosome is usually located near the nucleus of the cell and is composed of a pair of centrioles - two structures that lie perpendicular to each other. Each centriole serves as a cylinder composed of nine triplets of microtubules.
These centrioles play a significant role in cell division, with microtubules extending outward to help in separating DNA during division. The centrioles can also serve as the origin point for microtubules that extend as cilia or flagella. Therefore, in animal cells, the centrosome functions as not just a support structure, but also as a key component in cellular division and movement processes.
While both animal and plant cells have microtubule organizing centers, or MTOCs, it is only in animal cells that the centrosome is found as the associated complex. Thus, in brief, the centrosome is a critical structure in animal cells, responsible for the organization and regulation of microtubules.

Mrs. Fryer visits her nephrologist for an erythropoietin (EPO) injection for her anemia. She has Stage 3 chronic kidney disease, which is the cause of the anemia. Applying the coding concept from ICD-10-CM guideline I.A.13., what ICD-10-CM code(s) should be reported for the EPO injection
Answer:
N18.3, D63.1
Explanation:
Chronic Kidney Disease (CKD) is defined as the condition in human body that is known for by step by step loss of kidney function over a time being. N18.3 is usually given to patient in stage 3 of CKD. Epoetin injection is an artifical of human erythropoietin (EPO). naturally, EPO is produced in the body, by the kidneys largely. It energies or encourage the bone marrow to produce red blood cells. lack of EPO in the body can lead to severe occurence of anemia.D63.1 is usually called a chargeable ICD code. it is specifically used to show a diagnosis of anemia in chronic kidney disease.
Answer: N18.3, D63.1
The ICD-10-CM codes to be reported for Mrs Fryer EPO injection is N18.3, D63.1
N18.3 ; For Stage three kidney disease
F63.1 ; To show any sign of anaemia in people suffering from kidney disease.
Explanation: ICD-10-CM is a type of diagnosing tool they is used in the United states to code all diagnoses in all healthcare settings.
Anaemia is a blood disorder that is characterised by decrease in the quality and quantity of red blood cell in circulation in the body.
Erythropoetin is a hormone in the body that is triggered by decrease in the oxygen level in the blood,it is produced by the kidneys and it promotes the rate at which the bone marrow forms or produces red blood cell.
Mrs Fryer has stage 3 kidney disease which means that the kidney is grossly diseased and can't perform it's functions any longer one of which includes the production of erythropoetin,this erythropoetin is now administered to her artificially other than the natural one the body produces inorder to make up to the one the diseased kidney couldn't produce,this m erythropoetin will help the bone marrow to produce red blood cell in order to combat the anaemia that Mrs Fryer is facing/suffering from.
What muscle is responsible for contraction of the urinary bladder during micturition?
Answer:
Detrusor & Urethra
Explanation:
The major contractile muscle of the bladder is the detrusor. Urination involves either sustained contractions or short intermittent contractions of the detrusor along with contraction of the muscles in the urethra, the duct from the urinary bladder that conducts urine from the body.
What three changes must occur within the body to supply muscle cells with adequate sugar and oxygen
Answer:
The three changes that must occur within the body to supply muscle cells with adequate sugar and oxygen are:
The change of the sugars in the pancreas to be broken into simpler molecules.
The change of the air in the lungs to break it into elements to be distributed to the cells.
The change the muscle cells have to experience to be distributed with them.
Explanation:
To understand this answer we need to analyze the following. First of all, when the sugar enters the body it can't go straight to the cells. It needs to be broken into simpler molecules to be used by the cells. Also, the oxygen required by the cells enters the body inside the gasps of the air we do. However, we not only aspire oxygen so it has to be separated from the other elements and distributed. Also, the cells need to burn their energy to be distributed with more energy because if they don't do it, the sugar will be stored as fat.
In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:
6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy
How do these equations explain why the total amount of O2 and CO2 remains the same?
Answer:
it is H2O to the 3 power

Explanation:
Filtered fluid leaving the glomerular capillaries immediately enters the
Answer:
Answered below
Explanation:
The kidneys have a functional unit called the nephrons. Each nephron has a filter called the glomerulus. The glomerulus is an entanglement of blood capillaries encapsulated in the glomerular capsule. The glomerulus receives blood from the renal vessels. The capillaries of the glomerulus have tiny pores on their walls and they form a capillary bed where filtration occurs.
The filtered water and nitrogenous waste leaves the glomerular capillaries and immediately enter the proximal convoluted tubules where reabsorption occurs. From the proximal convoluted tubules it moves to the loop of Henle to the distal convoluted tubules and then to the collecting duct.
Answer:
It enters the efferent arterioles.
Explanation: The glomerulus receive blood supply from afferent arterioles.
The glomerulus filter blood and remove glucose, amino acids, water, salts, urea . Due to the high blood pressure , the solutes are forced to move the glomerulus space. It immediately enter the afferent arterioles and it passes through the tubule and specific substance are reabsorbed back to the blood.

Forelimbs carry the weight because of the angle between the stifle and hock in case of horsesForelimbs of whales helps in swimming whereas that of bats helps in swimming in the airThe actual forelimbs of these mammals do not seem to be optimally arranged because natural selection is generally limited to modifying structures that were present in previous generations and in previous specieswrite a food chain in which the hawk is a tertiary 3rd consumer:
A food chain is a linear pathway of energy flow in an ecosystem. To create a food chain where the hawk is a tertiary consumer, the chain can be: Grass -> Rabbit -> Snake -> Hawk.
Explanation:A food chain is a linear pathway of energy flow in an ecosystem. In order to create a food chain where the hawk is a tertiary consumer, we need to consider the trophic levels in the chain. The primary producers are the plants or phytoplankton, then the primary consumers are herbivores, followed by the secondary consumers that are usually carnivores. Finally, the tertiary consumers are carnivores that eat other carnivores. So, a food chain where the hawk is a tertiary consumer could be: Grass (producer) -> Rabbit (primary consumer) -> Snake (secondary consumer) -> Hawk (tertiary consumer).
In a food chain with a hawk as a tertiary consumer, the sequence is: grass (producer), grasshopper (primary consumer), frog (secondary consumer), and hawk (tertiary consumer).
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. Each organism in a food chain occupies a specific trophic level.
Here is an example of a food chain where the hawk is a tertiary consumer
Producers: Grass (photosynthetic organisms)Primary Consumers: Grasshopper (herbivores that eat grass)Secondary Consumers: Frog (carnivores that eat grasshoppers)Tertiary Consumers: Hawk (carnivores that eat the frog)In this food chain, nutrients and energy flow from the grass to the grasshopper, then to the frog, and finally to the hawk.

Which statement is true about mosses and gymnosperms? Group of answer choices Mosses are better adapted for desert habitats, whereas gymnosperms are better adapted for wet habitats. Mosses produce flowers in order to reproduce, whereas gymnosperms produce cones. Mosses rely on liquid water for fertilization, whereas gymnosperms do not need liquid water for fertilization. Mosses are primarily diploid in their adult form, whereas gymnosperms are primarily haploid.
Answer:
The statement that is true about mosses and gymnosperms is that mosses rely on liquid water for fertilization, whereas gymnosperms do not need liquid water for fertilization.
Explanation:
Mosses are photosynthetic plant species that have no stem, roots or leaves. The natural habitat of mosses is in humid places, as they have cells specialized in the absorption of water. Fertilization in mosses requires the presence of water, where male and female gametes join, giving rise to the release of spores when they reach maturity.
Gymnosperms are spermatophytes and vascular plants, producing seeds but lacking flowers. In their reproductive process, pollination and seed formation are involved, but their fertilization does not require liquid water to occur.

Which animals in the chart develop externally? Bird, Frog or human
Frogs are the animals from the options provided that develop externally. Birds lay hard-shelled eggs and humans develop internally within the uterus.
Explanation:The animals that develop externally according to the information provided are frogs. Birds and humans show internal development of their embryos. Frogs have a reproductive strategy known as ovipary where fertilization occurs outside of the mother's body, typically in a moist or aquatic environment, as highlighted by the reference to amphibians needing to lay their eggs in a wet environment prior to external fertilization.
Conversely, birds lay eggs with hardened shells due to high concentrations of calcium carbonate, and humans have a completely internal development process within the mother's uterus.

Answer:
D. A system.
Explanation:
Final answer:
A. An ecosystem refers to any network of relationships among various components that interact and influence each other through the exchange of energy, matter, or information, embodying a complex system of living organisms and their physical environment.
Explanation:
A. An ecosystem is any network of relationships among a group of components, which interact with and influence one another through the exchange of energy, matter, or information. Ecosystems encompass a dynamic complex of plant, animal, and microorganism communities, and the nonliving environment interacting as a functional system. This can range from a small water body like a pond to larger scales such as forests, continents, or the entire biosphere.
The functioning of ecosystems involves complex biotic and abiotic interactions that involve the exchange of matter and free energy. These systems are characterized by interaction networks that are hierarchical and often involve feedback mechanisms, whereby the behavior of ecosystems depends on the interactions between different organisms. At different levels, from cells and organisms to communities and ecosystems, these interactions are vital for the sustainability and functioning of biological systems.

-A population of birds with various size beaks eats seeds. Small seeds can be eaten by birds with small beaks. Larger,
thicker seeds can only be eaten by birds with larger thicker beaks. During a drought, only large thick seeds exist so only
the large, thick-beaked birds survive.
is it directional, disruptive or stabilizing selection
Answer:
Directional selection
Explanation:
The conditions of the environment change over time. These changes bring about the adaptation or not of species, hence, bringing about SELECTION. Selection is of different types but based on the example given in the question, DIRECTIONAL selection suits the description best. Directional selection is a kind of selection that occurs when an environmental change causes species with a particular phenotypic characteristics to be favored over the contrasting phenotype. Directional selection eventually results in the one-directional increase of species with a particular phenotype.
This is the case in this example involving a population of birds with different sizes of beaks (phenotype). The size of beaks determines the size of seed eaten by that bird i.e. small-beaked bird eats small seeds while birds with large and thick beaks eat large and thick seeds. A change in environmental conditions, which is drought, causes only large and thick seeds to be readily available. This means that only the birds with large and thick beaks can feed. Hence, the environment has selected or favored the birds with a large and thick beak over the ones with smaller beaks. This is an example of DIRECTIONAL selection because the selection goes in one phenotypic direction (birds with large, thick beaks).
The described situation is an example of directional selection, where the beak size in the bird population became larger due to selective pressures favoring larger beaks during a drought.
Directional selection occurs when one extreme phenotype is favored over others, causing the allele frequency to shift over time in the direction of that phenotype.
Before the drought, the bird population had a variety of beak sizes that allowed them to eat different types of seeds.During the drought, only large, thick seeds were available, which could only be eaten by birds with larger, thicker beaks.As a result, birds with smaller beaks died off, while birds with larger beaks survived and reproduced.Over time, the average beak size of the population increased as the genes for larger beaks became more frequent in the gene pool.complete question:
A population of birds with various size beaks eats seeds. Small seeds can be eatenby birds with small beaks. Larger, thicker seeds can only be eaten by birds with larger, thicker beaks. During a drought, only large thick seeds exist so only the large, thick-beaked birds survive. Does this so stabilizing selection, directional selection or disruptive selection?

Atmospheric carbon dioxide levels have been increasing gradually for many years. Scientists cite this increase as one of the main causes of climate change, which is a serious environmental problem for people all over the world. One component of a possible engineering solution to this problem is to use plants, algae, or phytoplankton to increase the global rate of photosynthesis. What scientific reasoning provides evidence that this solution could be effective?
A. Plants and other photosynthetic organisms change into fossil fuels over time.
B. Photosynthesis traps carbon dioxide in the soil.
C. Photosynthesis acts to remove carbon dioxide directly from the atmosphere.
D. Plants and other photosynthetic organisms provide food for consumers, who perform cellular respiration.
Plants and other photosynthetic organisms provide food for consumers, who perform cellular respiration.
What is Photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
Therefore, Plants and other photosynthetic organisms provide food for consumers, who perform cellular respiration.
